Why formulas differ

There is no single national formula for converting CGPA to percentage. Each board or university notifies its own. Using the wrong one can make a difference of several percentage points on a job or admission form, so always check what your institution says.

Common formulas

  • BPUT, Odisha: (CGPA − 0.5) × 10
  • CBSE and many universities: CGPA × 9.5
  • Some universities: CGPA × 10

For Utkal, Sambalpur, Berhampur and other Odisha universities, refer to the conversion rule printed on your mark sheet or the university's notification, then choose the matching option or enter a custom multiplier.

Percentage to CGPA

The reverse calculation simply inverts the formula. For CGPA × 9.5, divide the percentage by 9.5. For BPUT, divide by 10 and add 0.5.

Frequently asked questions
